Interesting... I just spent the last few hours updating covers in Calibre and was planning to export ("Save to Disk"), delete the library, and then reimport the books. Although now I'm worried those changes will be lost unless I convert first.
All of my books are in mobi format. Is that one of the formats that work?
Or should I do a conversion first?
